MINDA PERSONAL PROTECTION SYSTEM TX-400 KEY-FOB TRANSMITTER Operating Instruction Rev 1.0 June 2000 Tactical Technologies Inc. 1701 Second Ave Folsom, PA 19033 610-522-0106 www.tacticaltechnologies.
OVERVIEW Thank you for purchasing a MINDA TX-400 Transmitter, which uses a low-power microprocessor for ‘house-keeping’ and offers the following factory programmable options: • A Unit Identity Code (TX ID number 1,2,3,or 4) which will allow a single receiver to identify up to four different transmitters. • A very secure Family Identity Code, enabling secure use of multiple groups of transmitters and receivers together in the same location - without receiving alarms in ALL receivers.
If the first two pieces of data in the above message exactly match the information programmed into the ‘MINDA’ receiver, then the rest of the information will be decoded and displayed on the receiver's LEDs. If they do not match, the entire message is ignored. UNIT IDENTITY A MINDA TX-400 Keyfob Transmitter can have one of four possible Unit Identities (1, 2, 3 or 4) pre-programmed by the factory.
TRANSMISSION RANGE When using the MINDA system over a line-of-sight path, a range of greater than 100 yards is likely, whereas in a busy street, hotel, or indoors the range will be less. GETTING THE BEST RESULTS WITH MINDA To maximize the effectiveness and communications range of a 'MINDA' alarm system there are some simple 'tricks' that really do work and which, on all occasions when it is practical and convenient to use them, can be used to enhance its performance. These are....
TROUBLESHOOTING GUIDE If signals from a TX-400 transmitter are not being received by a MINDA receiver the following tests should be undertaken: 1.) Check that the transmitter is not out of receiver range by temporarily reducing the distance between the units to 10 yards or less. Begin to increase the distance again until signals transmitted are not received reliably. This will give a good indication of the likely maximum working range that can be achieved in the particular location used for these tests. 2.
